Varied-Line-Space Plane Grating Monochromator (VLSPGM) Beamline

Port 4A, 7 mrad
180-900 eV, SR-based XPS, total/partial yield, for soft X-ray photoemission
High-resolution soft X-ray beamline, 200-1200 eV range
5000 resolving power
NEXAFS, XAS, MCD measurements

Two cylindrical mirrors (M1 and M2) are located before the shielding wall. A spherical mirror and a varied line space plane grating (1000 gr/mm and 500 gr/mm) are employed with Hettrick and Underwood configuration covering the photon energy from 180 eV to 900 eV. Resolving power is ~5000 at nitrogen K-edge. Ultra-high-vacuum (UHV) multi-purpose XAS end station equipped with load-lock sample transfer system. A total electron yield measurement is offered.
